Heavyweight boxing & mixed martial arts ratings and commentary

Boxing Rankings - Top 500 All-Time Heavyweights

Ratings for fights from January, 1881 thru April, 2015. Note: for current Top 100click here

This list ranks fighters' all-time performance mainly by two criteria: 1) their 'peak moment' in the sport, and 2) by their cumulative wins over their career. The former is heavily influenced by big wins and avoiding losses, while the latter is unaffected by losing. Smaller adjustments are made to a) diminish the importance of one huge win on their career rating and b) penalize fighters with a great number of losses and reward those with excellent win/loss ratios. Points generally rise over the decades, reflecting the notion that today's fighters have a physical advantage; for the most part that edge is easily overcome by accomplishment in the ring, regardless of era.
